Note to OP, I'm really not a huge fan of people posting links to their own blogs... And in response to your essay, which by and large was tldr, I don't think many people run around saying that CS is math. Many computer scientists, as I'm quite sure you know, need to model their computable structures formally, show reductions or equivalences to other well-studied constructs, and then use the properties of these constucts to establish the expressiveness/complexity/whatever of their model. If outstanding questions remain then it can motivate basic research into the relevant mathematical field (particularly true with cryptography). These people "do math" - many other's from a CS background don't.
